Doom

CPU Role — cores, clocks, and how they relate to this game's results

The AMD Ryzen 5 5600 is a 6-core, 12-thread processor based on the Zen 3 architecture, built on TSMC's 7 nm process. It operates with a base clock of 3.50 GHz and a boost clock of 4.40 GHz, with a 65 W TDP. The processor carries 32 MB of shared L3 cache alongside 512 KB of L2 and 64 KB of L1 per core, and it supports dual-channel DDR4 memory with a bandwidth of 51.2 GB/s. For a title like Doom, which is a fast-paced FPS from 2016, the CPU's single-thread performance often dictates the ceiling in high-frame-rate scenarios, though the measured data here shows the GPU taking the lead at lower resolutions.

Benchmark results position this CPU at the 74th percentile among all processors, with an average benchmark score of 20,468. In synthetic tests, the Ryzen 5 5600 scores 6,564 in 3DMark's 16-thread test and 882 in single-thread, while Cinebench R23 yields 18,309 multi-core and 2,584 single-core. These numbers indicate a balanced part: strong enough for modern gaming workloads without being a bottleneck in a 2016-engine title like Doom, which is more sensitive to raw clock speed than to core count. The processor's nearest rivals in the database include the Intel Core Ultra 7 258V (0.1% higher average score) and the AMD Ryzen 5 8500G (0.2% higher), showing the 5600 sits in a tightly contested mid-range cluster.

In Doom specifically, the CPU's role becomes evident when examining the frame rate progression across settings at 1080p. At Low settings, the combo reaches 264 FPS average, and at Ultra it drops to 159 FPS. The gap between Low and Ultra at 1080p is 105 FPS (about 40% reduction), which is a larger relative drop than at higher resolutions. This suggests that at 1080p, the CPU is still feeding frames efficiently enough that the GPU's workload scaling with settings dominates the outcome. With a boost clock of 4.40 GHz and 12 threads, the Ryzen 5 5600 provides ample headroom for Doom's Vulkan-based engine, which is known for good multi-threaded scaling. The data shows no evidence of CPU-limited frame rates at any measured resolution, as even the highest FPS value (264 at 1080p Low) is well within the CPU's capability given its single-thread score of 1,085 in Cinebench R20.

GPU Role — VRAM, clocks, and how they relate to this game's results

The AMD Radeon RX 7700 XT is built on the RDNA 3.0 architecture with the Navi 32 chip, fabricated on a 5 nm process by TSMC. It features 3,456 shading units, 216 texture mapping units, and 96 raster output pipelines, along with 54 ray tracing cores. The GPU operates with a base clock of 1435 MHz, a game clock of 2171 MHz, and a boost clock of 2544 MHz. Memory is provided by 12 GB of GDDR6 on a 192-bit bus, yielding a bandwidth of 432.0 GB/s. The card's FP32 throughput is rated at 35.17 TFLOPS, and it draws up to 245 W.

In the database, the RX 7700 XT sits at the 67th percentile among all GPUs, with an average benchmark score of 22,549. Its nearest rivals include the NVIDIA GeForce RTX 5060 Mobile (0.5% higher score) and the RTX 2080 (1.5% higher), placing it in a competitive performance tier. The GPU's PassMark G3D score of 22,547 and 3DMark Steel Nomad DX12 score of 3,316 reflect its DirectX 12 capability, which is relevant for Doom's Vulkan rendering path.

Examining the measured FPS data, the GPU's influence is most pronounced at 4K resolution. At 3840x2160, the RX 7700 XT delivers 68 FPS average on High settings, 81 FPS on Medium, and 93 FPS on Low, but drops to 56 FPS on Ultra. The 12 GB VRAM buffer is more than sufficient for Doom's textures at any setting, as the game's 2016 release date means asset sizes are modest by modern standards. The GPU's memory bandwidth of 432.0 GB/s also ensures that the 192-bit bus does not become a limiting factor at 4K, where bandwidth demands increase. The data shows that the GPU is the primary scaling component: as settings move from Low to Ultra, the frame rate drops by roughly 40% at 4K (93 to 56 FPS), which is a characteristic of GPU-bound rendering rather than CPU or memory constraints.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured FPS data reveals a clear pattern of GPU-bound scaling across resolutions. At 1080p High, the combo averages 194 FPS; at 1440p High, it drops to 126 FPS; and at 4K High, it falls to 68 FPS. This represents a 35% reduction from 1080p to 1440p, and a further 46% reduction from 1440p to 4K. The same trend holds across all settings. For Medium settings, the progression is 230 FPS at 1080p, 149 FPS at 1440p, and 81 FPS at 4K — a 35% drop followed by a 46% drop. Low settings show 264 FPS at 1080p, 171 FPS at 1440p, and 93 FPS at 4K, with similar percentage reductions.

This scaling behavior is characteristic of a system where the GPU is the limiting factor at higher resolutions. If the CPU were the bottleneck, we would expect to see less separation between resolutions, as the frame rate would plateau once the CPU's maximum throughput is reached. Instead, the consistent 35-46% drops at each step indicate that the RX 7700 XT's rendering workload is scaling directly with pixel count. The CPU's role becomes more relevant at 1080p, where the frame rates are high enough (194-264 FPS) that per-frame CPU overhead could matter, but the data does not show any plateauing effect.

Another way to interpret the scaling is through the ratio of FPS at different resolutions. At High settings, the 1440p to 1080p ratio is 0.65 (126/194), and the 4K to 1440p ratio is 0.54 (68/126). These ratios are not perfectly proportional to pixel count — 4K has 2.25 times the pixels of 1440p, yet the FPS drops by only about half — which suggests the GPU has some headroom in memory bandwidth or shading capacity that prevents a full linear scaling penalty. The 12 GB VRAM and 432.0 GB/s bandwidth are sufficient to keep the GPU fed even at 4K, where the average FPS remains playable at 68 FPS on High.

Settings Recommendations — which preset gives the best experience per the measured rows

Based on the measured FPS data, the Medium preset offers the most balanced experience across all resolutions. At 1080p Medium, the combo achieves 230 FPS average with a minimum of 196 FPS, which is well above the 144 Hz refresh rate common on gaming monitors. At 1440p Medium, the average is 149 FPS with a minimum of 127 FPS, still comfortably above 120 FPS for high-refresh displays. At 4K Medium, the average is 81 FPS with a minimum of 69 FPS, which is playable on 60 Hz displays but not ideal for competitive play.

The High preset provides a visual upgrade with only a modest FPS cost at lower resolutions. At 1080p High, the average is 194 FPS (36 FPS less than Medium), and at 1440p High, it is 126 FPS (23 FPS less). However, at 4K High, the average drops to 68 FPS, which is marginal for smooth gameplay. The Ultra preset is the most demanding, with 159 FPS at 1080p, 103 FPS at 1440p, and 56 FPS at 4K. The 4K Ultra result falls below the 60 FPS threshold, making it unsuitable for consistent frame pacing.

The Low preset yields the highest frame rates — 264 FPS at 1080p, 171 FPS at 1440p, and 93 FPS at 4K — but it sacrifices visual fidelity. For a game like Doom, which relies on fast motion and clear enemy visibility, the Medium preset strikes the best compromise: it maintains high frame rates at 1080p and 1440p while providing adequate visual detail. At 4K, Medium is the recommended choice because it stays above 60 FPS with a minimum of 69 FPS, whereas High and Ultra dip below that threshold.
